In chemistry, pH (/piËËeÉªtÊ/) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the logarithm to base 10 of the molar concentration, measured in units of moles per liter, of hydrogen ions.
The Simple Definition. pH is a logarithmic measure of hydrogen ion concentration, originally defined by Danish biochemist S ren Peter Lauritz S rensen in 1909 [ 1 ]. pH = -log[H+]. where log is a base-10 logarithm and [H+] is the concentration of hydrogen ions in moles per liter of solution.According to the Compact Oxford English Dictionary, the p stands for the German word for power, potenz, so pH is an abbreviation for power of hydrogen [ 2 ].here log is a base-10 logarithm and [H+] is the concentration of hydrogen ions in moles per liter of solution. According to the Compact Oxford English Dictionary, the p stands for the German word for power, potenz, so pH is an abbreviation for power of hydrogen [ 2 ].
